Benefits of technology

The present invention provides an image-forming apparatus that can prevent the accuracy of image formation onto a recording material from being reduced, even when there is an inflow of heated air from the heating unit to the image-former. This is particularly important in recent configurations where the heating unit and image-former are close to each other, which can cause deterioration in image formation accuracy.

Problems solved by technology

Therefore, in the configuration of the image-forming apparatus according to above-described Patent Literature 2, for example, deterioration in the accuracy of the landing position due to the inflow of the heated air to the image-former is caused.

first embodiment

1. First Embodiment of Image-Forming Apparatus

[0034]Hereinafter, a specific embodiment of an image-forming apparatus of the present invention will be described.

[0035]FIG. 1 illustrates a rough schematic diagram of an image-forming apparatus of a first embodiment. The image-forming apparatus 1 illustrated in FIG. 1 is provided with a recording-material supplier 10, a heating unit 20, a shielding member 70, an image-former 30, a recording-material discharger 40, and an unshown controller 50 (see FIG. 3). The image-forming apparatus 1 illustrated in FIG. 1 is a side view of the image-forming apparatus 1 viewed in the direction which is orthogonal to a recording-material conveyance direction. Note that, in the diagram, flows of air in the heating unit 20 and the image-former 30 are illustrated by arrows.

[0037]The recording-material supplier 10 is provided with a placement tray 11, a sending roller 12, etc. The recording-material supplier 10 stocks reco...

second embodiment

2. Second Embodiment of Image-Forming Apparatus

[0093]Next, a second embodiment of an image-forming apparatus will be described.

[0094]In the above described first embodiment, the example in which the shielding member includes one flat-plate-like member is described. However, the shielding member may be configured to be a combination of plural flat-plate-like members. Therefore, as the image-forming apparatus of the second embodiment, an example provided with a shielding member including plural flat-plate-like members will be described. Note that, in the second embodiment, a configuration similar to that of the above described first embodiment can be applied except for the configuration of the shielding member. Therefore, detailed descriptions about the configuration similar to that of the above described first embodiment will be omitted.

[0096]FIG. 4 illustrates a partial configuration of the heating unit 20, a shielding member 71, and the image-former 30 corre...

third embodiment

3. Third Embodiment of Image-Forming Apparatus

[0103]Next, a third embodiment of an image-forming apparatus will be described.

[0104]In the above described first embodiment and the second embodiment, the example in which the flat-plate-like member is used as the shielding member has been explained. However, the shielding member is not limited to a flat-plate-like member as long as the shielding member is configured to be able to shield the heated air. Therefore, as the image-forming apparatus of the third embodiment, an example provided with a shielding member including a roller will be described. Note that, in the third embodiment, a configuration similar to that of the above described first embodiment can be applied except for the configuration of the shielding member. Therefore, detailed descriptions about the configuration similar to that of the above described first embodiment will be omitted.

Abstract

An image-forming apparatus that can restrict reduction in the accuracy of image formation onto a recording material is provided. An image-forming apparatus includes an image-former that discharges ink to a conveyed recording material; a recording-material heating unit that is disposed in an upstream side of the image-former; a chassis that covers the recording-material heating unit; and a shielding member that is disposed between the chassis and the image-former and shields inflow of air, which is discharged from a recording-material outlet, into the image-former.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present invention claims priority under 35 U.S.C. ยง 119 to Japanese Application, 2021-072734 filed on Apr. 22, 2021, the entire contents of which being incorporated herein by reference.BACKGROUNDTechnological Field[0002]The present invention relates to an image-forming apparatus.Description of the Related Art[0003]There is an image-forming apparatus which discharges ink onto a recording material to form an image on the recording material. Many of the inks used in the image-forming apparatus have differences in a final state such as color development or glazing depending on the temperature state, etc. after landing on the recording material. In such a case, temperature control for heating the recording material to an appropriate temperature is important.[0004]As a method of heating the recording material before ink landing to an appropriate temperature, a configuration in which a contact-type heating unit using a heating roller or the ...
